Brighton | May 21, 1991 |
A practice round and firearm system wherein the round [10] includes a casing [11] forming a cavity [16] to receive a movable insert [20]. The insert forms a recess holding a projectile [30] and by detonation of a primer cap [36], the resulting expanding gases propel the insert and projectile forward toward the barrel passage until the insert strikes the chamber forward wall [46 to allow the projectile to continue through the barrel passage. The casing and insert thereafter move rearward with the slide [50 for automatic extraction of the spent casing from the chamber [44].
